STRUCTURE AND FUNCTIONS A color TFT (thin film transistor) LCD module is comprised of a TFT liquid crystal panel structure, LSIs for driving the TFT array, and a backlight assembly. The TFT panel structure is created by sandwiching liquid crystal material in the narrow gap between a TFT array glass substrate and a color filter glass substrate. After the driver LSIs are connected to the panel, the backlight assembly is attached to the backside of the panel. RGB (red, green, blue) data signals from a source system is modulated into a form suitable for active matrix addressing by the onboard signal processor and sent to the driver LSIs which in turn addresses the individual TFT cells. Acting as an electro-optical switch, each TFT cell regulates light transmission from the backlight assembly when activated by the data source. By regulating the amount of light passing through the array of red, green, and blue dots, color images are created with clarity.

POWER SUPPLY DESIGN (1) Please note that the supply voltage must not be applied while the control signals (SEL, UP, DOWN, EXIT, BRT+ and BRT-) are connected to GND. Otherwise the module may cause malfunction. (2) If the power supply voltage is applied while UP and DOWN are connected to GND, the input control signals become ineffective. In this case, please turn off the power once and turn on the power while UP and DOWN are connected to GND again. (3) Inverter current wave Inverter current wave is as follows.
1400 (mA) 0 (A) Duty Luminance control frequency
Maximum luminance control: 100% Minimum luminance control: 20% Luminance control frequency = Input Vsync frequency x K Input Vsync frequency 75 Hz: K = 4.6 Input Vsync frequency > 75 Hz: K = 3.6
(4) Ripple of supply voltage
VDD (for logic and LCD driver) Acceptable range 100 mVp-p VDDB (for backlight) 200 mVp-p
Remark The acceptable range of ripple voltage includes spike noise. Example of the power supply connection a) Separate the power supply

1. Out of specification. These modes are less display quality than other guaranteed modes. Even if the preset timing is entered, a little adjustment of the functions such as Horizontal period, CLK-delay and display position, are required. The adjusted values are memorized in every preset No. This module recognizes the synchronous signals with near preset timing of the frequency of Hsync, Vsync, even in the case that the signals other than the preset timing that were entered. For instance, it is displayed with presetting number 5 in the case of 640 x 480 dot, Hsync: 37.861 kHz, Vsync: 72.809 Hz an example). Adopt the evaluation, because adjustment may not fit, in the case that the magnifying ratio differs, in the case that you use it with except for the display timing that was preset.

EXPANSION FUNCTION (REFERENCE) (1) How to use expansion mode Expansion mode is a function to expand screen. For example, VGA signal has 640 x 480 pixels. But, if the display data can expanded to 2.0 times vertically and horizontally,VGA screen image can be displayed fully on the screen of SXGA resolution. This LCD module has the function that expands vertical direction as shown in the following table. And expanding horizontal direction is possible by setting input CLK frequency equivalent to the magnification. It is necessary to make this CLK outside of this LCD module. Please adopt this mode after evaluating display quality, because the appearance in the expansion mode is happened to be relatively bad in some cases. The followings show the display magnifications for each mode.
Magnification Input display SXGA XGA SVGA VGA VGA text MAC Number of pixels Vertical 1280 x 1024 1024 x 768 800 x 600 640 x 480 720 x 400 832 x 624 1 1.25 1.6 2.0 2.5 1.6 Horizontal Note 1 1.25 1.6 2.0 1.7 1.5
Note The horizontal magnification multiples the input clock (CLK). Input CLK = system CLK x horizontal magnification. Example In case of SXGA and VGA, CLK frequency can be decided as follows. SXGA: (system CLK (108.0 MHz)) x 1.0 = 108.0 MHz. VGA : (system CLK (25.175 MHz)) x 2.0 = 50.35 MHz.

CAUTION
This figure is a mark that you will get an electric shock when you make a mistake to operate.
This figure is a mark that you will get hurt when you make a mistake to operate
CAUTION
Do not touch an inverter, on which is stuck a caution label, while the LCD module is under the operation, because of dangerous high voltage.
(1) Caution when taking out the module a) Pick the pouch only, in taking out module from a carrier box. (2) Cautions for handling the module a) As the electrostatic discharges may break the LCD module, handle the LCD module with care against electrostatic discharges. b) c) As the LCD panel and backlight element are made from fragile glass material, impulse and pressure to the LCD module should be avoided. As the surface of polarizer is very soft and easily scratched, use a soft dry cloth without chemicals for cleaning. d) Do not pull the interface connectors in or out while the LCD module is operating. e) Put the module display side down on that horizontal plane. f) Handle connectors and cables with care. the LCD panel would be damaged. h) The torque to mounting screw should never exceed 0.392 N*m (4 kgf*cm). (3) Cautions for the atmosphere a) Dew drop atmosphere should be avoided. b) Do not store and/or operate the LCD module in a high temperature and/or high humidity atmosphere. Storage in an electro-conductive polymer packing pouch and under relatively low temperature atmosphere is recommended. c) This module uses cold cathod fluorescent lamps. conspicuously at low temperature. d) Do not operate the LCD module in a high magnetic field. (4) Caution for the module characteristics a) Do not apply fixed pattern data signal for a long time to the LCD module at product aging. Applying fixed pattern for a long time may cause image sticking. Therefore, the life time of lamps becomes short g) When the module is operating, do not lose CLK, Hsync or Vsync signal. If any one of these signals is lost,

(5) Other cautions a) Do not disassemble and/or reassemble LCD module. b) Do not readjust variable resistors or switches, etc. c) When returning the module for repair or etc, please pack the module not to be broken. We recommend to the original shipping packages. Liquid Crystal Display has the following specific characteristics. There are not defects or malfunctions. * The display condition of LCD module may be affected by the ambient temperature. * The LCD module uses cold cathode tube for backlighting. Optical characteristics, like luminance or uniformity, will change during time. * Uneven brightness and/or small spots may be noticed depending on different display patterns.

No license, either express, implied or otherwise, is granted under any patents, copyrights or other intellectual property rights of NEC Corporation or others. While NEC Corporation has been making continuous effort to enhance the reliability of its Electronic Components, the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or property arising from a defect in an NEC Electronic Components, customers must incorporate sufficient safety measures in its design, such as redundancy, fire-containment, and anti-failure features. NEC devices are classified into the following three quality grades: "Standard", "Special", and "Specific". The Specific quality grade applies only to devices developed based on a customer designated "quality assurance program" for a specific application. The recommended applications of a device depend on its quality grade, as indicated below. Customers must check the quality grade of each device before using it in a particular application. Standard: Computers, office equipment, communications equipment, test and measurement equipment, audio and visual equipment, home electronic appliances, machine tools, personal electronic equipment and industrial robots Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster systems, anti-crime systems, safety equipment and medical equipment (not specifically designed for life support) Specific: Aircrafts, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems or medical equipment for life support, etc. The quality grade of NEC devices is "Standard" unless otherwise specified in NEC's Data Sheets or Data Books. If customers intend to use NEC devices for applications other than those specified for Standard quality grade, they should contact an NEC sales representative in advance. Anti-radioactive design is not implemented in this product.
